Question

which is big level singing or playing piano​

Answer 1

From experience, it's easier to learn singing. It's because it's easier to learn songs, and more specifically sing them well. It also depends on the instrument and what you want to use it for. If you want to play piano and sound like Biethoven, then it will surely be harder than singing.

Answer 2

Answer: To me, it was Piano because I don't really like singing. So I guess it's just which one you like the most. Which ever one your most connsistant in.
